Can you drink Atkins shakes on the keto diet? Here's what you need to know

3 min read

According to the official Atkins website, many of their shakes are considered compatible with a low-carb and ketogenic lifestyle. This often-debated topic requires a closer look at the nutritional content to determine if you can drink Atkins shakes on the keto diet without jeopardizing ketosis.

Quick Summary

Atkins shakes can fit into a keto diet, but macros must be checked carefully. While low in net carbs and sugar, high protein could impact ketosis. Consider ingredients and track your daily intake.

Key Points

  • Check Net Carbs: Most Atkins shakes are low in net carbs (often 2-4g), making them compatible with keto if you track your daily totals.

  • Watch Protein Intake: The moderate-to-high protein levels in some Atkins shakes could potentially disrupt ketosis through gluconeogenesis if consumed in excess.

  • Customize for Keto: To make shakes more keto-friendly, add healthy fats like MCT oil or almond butter and use unsweetened nut milk to increase fat content.

  • Read All Ingredients: Be mindful of artificial sweeteners, sugar alcohols, and other additives that might cause side effects or impact ketosis for sensitive individuals.

  • Track Your Macros: Treat Atkins shakes as a supplementary tool within your broader keto diet, carefully tracking their impact on your daily carb, protein, and fat macros.

  • Prioritize Whole Foods: While convenient, packaged shakes should not replace a diet primarily focused on whole, unprocessed keto-friendly foods.

Understanding the Atkins vs. Keto Difference

While both the Atkins and ketogenic diets focus on low-carb eating, their structures and ultimate goals differ significantly. The ketogenic diet aims to keep your body in a constant state of ketosis by severely restricting carbohydrates, typically to under 50 grams per day. The Atkins diet, on the other hand, consists of multiple phases where carbohydrate intake is gradually increased over time. This means that while both are low-carb, the strictness required for keto is often higher than in the later phases of Atkins.

Can a Product Designed for One Diet Work for Another?

This is where the compatibility of Atkins shakes and the keto diet comes into question. Many Atkins products are formulated to be low in net carbs and sugar to support weight management. However, a core principle of keto is not just low carbs, but also moderate protein intake. Excessive protein consumption can lead to gluconeogenesis, a metabolic process where excess protein is converted into glucose, potentially kicking your body out of ketosis.

What to look for on the label

If you choose to incorporate Atkins shakes, reading the label is non-negotiable. Here's a quick checklist:

  • Net Carbs: Look for shakes with 2-4 grams of net carbs or less per serving. Net carbs are calculated by subtracting dietary fiber from the total carbs.
  • Protein Content: The amount of protein varies significantly between Atkins shakes. Some contain 15g, while others contain 30g. A high-protein shake might push you over your daily moderate protein target for a standard keto diet.
  • Ingredients: Pay attention to ingredients like artificial sweeteners, sugar alcohols (like maltitol), or soluble corn fiber, which might cause digestive issues or unexpectedly raise blood sugar for some individuals.

Comparison: Atkins Shakes vs. Ideal Keto Macros

Feature Typical Atkins Shake (e.g., Milk Chocolate Delight) Ideal Keto Diet Macro Balance Consideration for Keto Dieters
Net Carbs 2g per serving < 50g daily Good: Fits well within daily carb limits, but watch total intake.
Protein 15g per serving ~20-25% of total calories Moderate Concern: Can be an efficient protein boost, but must be balanced with other meals to avoid excess protein.
Fat ~9g per serving ~70-75% of total calories High Concern: Significantly lower in fat than a typical keto meal replacement.
Satiety High protein helps with fullness. High fat and moderate protein provide strong satiety. Adjustable: May need added fats (e.g., MCT oil) to increase satiety and meet fat goals.

Optimizing an Atkins Shake for Keto

If you decide that Atkins shakes align with your carb and protein limits, you may still need to modify them to better fit your keto macros. Since they are often lower in fat than a traditional keto meal, consider the following additions:

  1. Add healthy fats: Blend in a tablespoon of MCT oil, coconut oil, or a nut butter to increase the fat content.
  2. Use a keto-friendly liquid: Mix protein powder varieties with unsweetened almond milk or coconut milk instead of dairy milk to minimize carbs.
  3. Incorporate low-carb mix-ins: Add a handful of spinach or half an avocado for extra nutrients and healthy fats without many carbs.

Potential Drawbacks and Considerations

While convenience is a major benefit, there are some potential drawbacks to relying on packaged shakes. The focus on whole foods is often highlighted as a healthier approach to nutrition. Some shakes contain artificial sweeteners and additives that may not be suitable for everyone and could trigger sensitivities. For the purest form of nutrition, a whole-food approach is always recommended. For those looking for pre-made alternatives, reading labels and choosing shakes with clean ingredients is key. However, when time is a factor, an Atkins shake can be a strategic, convenient option.

Conclusion: A Tool, Not a Crutch

So, can you drink Atkins shakes on the keto diet? Yes, for most people, they can be part of a ketogenic diet, but they require careful management. The low net carb and low sugar content make many of them suitable. However, the moderate-to-high protein content means you must track your intake to prevent gluconeogenesis. Atkins shakes are best viewed as a convenient tool for an occasional meal or snack, not as a primary component of your diet. Always prioritize whole, unprocessed foods and remember to listen to your body and its response to these products. For personalized advice, it's always wise to consult a healthcare professional or registered dietitian before making significant changes to your diet.

Frequently Asked Questions

No, not all Atkins shakes are universally keto-friendly. While most are low-carb, their protein content can be too high for some strict keto dieters. You must read the specific nutritional label and ingredient list for each product.

The main difference is carb intake over time. The ketogenic diet maintains very low carb intake indefinitely to stay in ketosis, whereas the Atkins diet gradually increases carb allowance through its phases.

Yes, if consumed in excess, protein can be converted into glucose through a process called gluconeogenesis, which can raise blood sugar and potentially disrupt ketosis.

You can add healthy fats like MCT oil, heavy cream, or avocado to increase the fat content. You can also mix it with unsweetened almond or coconut milk to manage liquid carbs.

Yes, many Atkins shakes use artificial sweeteners (like sucralose and acesulfame potassium) and may contain soluble corn fiber. These ingredients might cause digestive issues or other side effects in some individuals.

Many Atkins shakes are formulated to have a very low net carb count, often between 2 and 4 grams per serving, when using the calculation of Total Carbs minus Fiber.

You can use an Atkins shake as a meal replacement, but be aware that it might be lower in fat than a typical keto meal. You may need to supplement with added fats to feel full and meet your fat macro goals.
